Meta Box

Hi Long, i still see this: Invalid form submission, please try again.
but, i have no validation on my form.

My shortcode is:
[mb_user_profile_register label_username="Usuario" role="subscriber" id="campos-usuario" label_submit="REGISTRARME" password_strength="false" confirmation="Su cuenta fue creada exitosamente! Haga click en el botón Ingreso" redirect="/registro-exitoso/" label_password="Clave" label_password2="Confirmar clave"]

do you need my user and password to access admin section?

Hi Long, I don't understand what you mean by the code with which I created the field... I use the visual metabox builder, attached screenshot

I put here the solution, in case someone else needs it.
Call in View: mb.letras_abecedario()
then, in config.php on child theme:

// ****************************************************************************
function letras_abecedario() {
 $letra = htmlspecialchars($_GET["letra"]); 
 $paged = ( get_query_var( 'paged' ) ) ? get_query_var( 'paged' ) : 1;
 $args = array(
  'post_type'      => 'autor-de-frase',
  //'category_name'  => 'marketing-resources',
  'order'          => 'DESC',
  'orderby'        => 'date',
  'posts_per_page'      => '15', //how many posts you need
  'paged'          => $paged, //add the 'paged' parameter
'meta_query' => array(
       array(
          'key'=>'letra',
          'compare'=>'=',
          'value'=>$letra
      )
     )
);
  $parent = new WP_Query( $args );
  if ( $parent->have_posts() ) : ?>
   <?php while ( $parent->have_posts() ) : $parent->the_post(); ?>
<a>" ><?php echo rwmb_meta( 'apellido_del_autor' ); ?>,    <?php echo rwmb_meta( 'nombre_del_autor' ); ?></a>
    <?php echo rwmb_meta( 'bio_del_autor_de_frase' ); 
     echo ' - ';
     echo rwmb_meta( 'algo_sobre_el_autor' ); 
    ?>
    <?php
    //echo '<br>';
    //echo rwmb_meta( 'profesion-del-autor' );
    //echo get_the_term( $post->ID, 'apellido_del_autor');
echo ' <hr style="margin:10px 0px"> '; //Your code goes here 
?> 
<?php endwhile;  ?>
    <br>
    <?php previous_posts_link( '&laquo; Anterior', $parent->max_num_pages) ?>  <?php next_posts_link( 'Siguiente &raquo;', $parent->max_num_pages) ?>
     <br><br>
  <?php else: ?>
    <p>No posee autores</p>
  <?php endif; ?>
<?php wp_reset_query(); 
}

Hi Long, thanks.
This is beyond my knowledge and I don't understand what I should do.
Would you be so kind as to share an example? I have seen that in some answers you record a step by step video. That would be really great.

I have seen what you recommend, for example:
<?php
//Protect against arbitrary paged values
$paged = ( get_query_var( 'paged' ) ) ? absint( get_query_var( 'paged' ) ) : 1;

$args = array(
'posts_per_page' => 5,
'category_name' => 'gallery',
'paged' => $paged,
);

$the_query = new WP_Query( $args );
?>
<!-- the loop etc.. -->

but I have no idea how to insert it into views with twig.
I hope you can help me with this.
Thank you very much.
